Coefficients of the \(q\)-expansion are expressed in terms of a basis \(1,\beta_1,\ldots,\beta_{5}\) for the coefficient ring described below. We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + \beta_1 q^{2} + (\beta_{5} - \beta_{3} - \beta_1) q^{3} + ( - \beta_{5} + \beta_{4} - 2 \beta_{3} + \cdots - 3) q^{4} + (2 \beta_{5} - 2 \beta_{4} + \beta_{3} + \cdots + 3) q^{6} + (\beta_{4} - 1) q^{7}+ \cdots + (3 \beta_{5} - 3 \beta_{4} + 2 \beta_{3} + \cdots + 5) q^{99}+O(q^{100}) \) Copy content Toggle raw display
